Linux Distros Unpatched Vulnerability : CVE-2026-28688

medium Nessus Plugin ID 301749

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a heap-use-after-free vulnerability exists in the MSL encoder, where a cloned image is destroyed twice. The MSL coder does not support writing MSL so the write capability has been removed. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. (CVE-2026-28688)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
